Searching for Population III stars with line intensity mapping cross-correlations
Sahil Hegde, Guochao Sun, Julian B. Muñoz +1
Decades of searches for Population III stars in individual galaxies have yielded a few potential candidates, but a statistically robust characterization of the demographics of the…
Do we understand the star formation history of the universe?
Sahil Hegde, Steven R. Furlanetto, Smadar Naoz
The evolving relationship between a galaxy's mass and star formation rate -- the so-called `star-forming main sequence' (MS) -- provides a critical benchmark for understanding star…
Efficient semi-analytic modelling of Pop III star formation from Cosmic Dawn to Reionization
Sahil Hegde, Steven R. Furlanetto
The quest to find the first stars has driven astronomers across cosmic time, from hopes to identify their signatures in their heyday at cosmic dawn to deep searches for their remna…
A hidden population of active galactic nuclei can explain the overabundance of luminous objects observed by JWST
Sahil Hegde, Michael M. Wyatt, Steven R. Furlanetto
The first wave of observations with JWST has revealed a striking overabundance of luminous galaxies at early times () compared to models of galaxies calibrated to pre-JWST da…
A self-consistent semi-analytic model for Population III star formation in minihalos
Sahil Hegde, Steven R. Furlanetto
The formation of the first stars marks a watershed moment in the history of our universe. As the first luminous structures, these stars (also known as Population III, or Pop III st…
Modeling Strong Lenses from Wide-Field Ground-Based Observations in KiDS and GAMA
Shawn Knabel, B. W. Holwerda, J. Nightingale +13
Despite the success of galaxy-scale strong gravitational lens studies with Hubble-quality imaging, the number of well-studied strong lenses remains small. As a result, robust compa…
Reorientation Rates of Structural and Kinematic Axes in Simulated Massive Galaxies and the Origins of Prolate Rotation
Sahil Hegde, Greg L. Bryan, Shy Genel
In this work, we analyze a sample of 4000 massive ( at ) galaxies in TNG300, the box of the IllustrisTNG simulation suite…
Classifying Signatures of Sudden Ionospheric Disturbances
Sahil Hegde, Monica G. Bobra, Philip H. Scherrer
Solar activity, such as flares, produce bursts of high-energy radiation that temporarily enhance the D-region of the ionosphere and attenuate low-frequency radio waves. To track th…
